I have a dataset with station observation in csv file. Output is nothing cf.head()

from eofs.xarray import Eof
ds = cf.to_xarray()
solver = Eof(ds["ci"])
eof_ci = solver.eofsAsCorrelation(neofs=1)

here is eof_ci：

<xarray.DataArray 'eofs' (mode: 0, Lat: 154, Lon: 166)> array([], shape=(0, 154, 166), dtype=float64) Coordinates:

There isn't enough information here to act on. What is the shape of ds["ci"] and what coordinates does it have?
